Transitioning to a zero-carb diet is a massive metabolic shift for your body. If you’ve just started the carnivore diet and find yourself dealing with headaches, fatigue, or muscle cramps, you are likely experiencing the "keto flu." The good news? It’s entirely preventable.

My Personal Lesson with Salt

During my first week on carnivore, I felt exhausted. I thought the diet wasn't working for me. I had a crushing headache on Day 4 because I was still salting my food lightly—a habit from my old "healthy" diet. Once I started generously salting my steaks and drinking salty bone broth, my energy skyrocketed literally within an hour. Don't fear the salt!

Why Electrolytes Dump on Carnivore

When you stop eating carbohydrates, your insulin levels drop significantly. This is great for fat burning, but insulin also signals your kidneys to hold onto sodium. As insulin drops, your kidneys flush out sodium, and water follows. This leads to a rapid loss of water weight (which is why you look leaner so fast), but it also flushes out potassium and magnesium.

How to Optimize Your Electrolytes

• Sodium: This is the big one. You need significantly more salt than you think. Aim for 2-3 extra grams of sodium per day during adaptation. Use high-quality sea salt or Redmond Real Salt.
• Potassium: Meat is naturally rich in potassium. The key to keeping your potassium levels stable is to not lose your sodium. If sodium drops, your body will excrete potassium to maintain the balance.
• Magnesium: If you experience muscle cramps or poor sleep, a magnesium supplement (like magnesium glycinate) before bed can be a game-changer.

Pro Tip: If you feel a headache coming on, put a pinch of salt directly on your tongue and drink a glass of water. If you feel better in 15 minutes, it was an electrolyte issue.
